Abstract

The invention discloses water splashing type polyvinyl chloride artificial leather. The water splashing type polyvinyl chloride artificial leather comprises a coating layer, a surface layer and a basecloth layer, wherein the surface layer is arranged on the base cloth layer, the coating layer is further arranged on the surface of the surface layer, and the coating layer comprises, by weight, 100parts of modified waterborne polyurethane emulsion, 25-45 parts of deionized water, 0.2-1.5 part of graphene oxide, 0.1-1 part of a surfactant, 0.1-1 part of a defoaming agent and 0.5-1.5 parts of flatting agents; and the modified waterborne polyurethane is prepared from isophorone diisocyanate and polyether as raw materials, hydroxypropyl-terminated fluorine-containing polysiloxane is used as a modifier, dimethylolpropionic acid is used as a hydrophilic monomer, and trimethylolpropane is used as chain extension monomer synthesis. The invention also discloses a preparation method of the water-splashing polyvinyl chloride artificial leather. The artificial leather has higher water splashing and excellent water repellency, and has better wear resistance, higher strength and better surface gloss.

Description

technical field [0001] The invention belongs to the technical field of artificial leather, in particular to a water-repellent polyvinyl chloride artificial leather and a preparation method thereof. Background technique [0002] PVC artificial leather has the advantages of hydrolysis resistance, wear resistance, scratch resistance, acid and alkali resistance, flame retardant, etc., and has a relatively low price advantage. It has been widely used in luggage, automobiles, sofa cushions, shoe materials, stationery and other industries. [0003] With the development of social economy and the continuous improvement of people's living standards, people have higher and higher requirements for basic necessities of life, especially shoes, bags, sofas, etc. commonly used in daily life, need to have good moisture permeability, wear resistance Scratch resistance, softness, etc., but also has excellent waterproof performance. Existing artificial leather still cannot satisfy the market d...
